HDMI cable spec

Every HDMI version, what it carries, how far it goes.

A reference table of every published HDMI version: peak bandwidth, max resolution + frame rate, audio return support, CEC, and the practical max passive-copper distance for the version's headline format.

reading the table
  • Bandwidth is the peak TMDS / FRL link rate. Real-world headroom is lower because of 8b/10b or 16b/18b coding overhead.
  • Max passive copper is the practical distance off-the-shelf cables hold the headline format reliably. Active cables, optical, or extenders push much further.
  • eARC supports lossless multi-channel formats (TrueHD Atmos, DTS-HD MA); ARC tops out at compressed 5.1.
  • Cable categories: Standard (1.4 SD/HD), High-Speed (1.4 up to 4K30), Premium High-Speed (2.0), Ultra High-Speed (2.1, 48 Gbps), Ultra96 (2.2, 96 Gbps).
